^aPre-implementation phase: Jan 2014–April 2016. Y1 = year 1 (May 2016–April 2017). Year 2 = May 2017–May 2018 (cost not shown). Implementation phase = year 1 and year 2. Annual average costs = (year 1 + year 2)/2
^bTransport: Recurrent transport costs include vehicle operating costs only (fuel, insurance, maintenance and repairs). Capital transport costs include vehicle purchase costs only
^cCost and insurance and freight for bacterial larvicide (Bti: Bacillus thuringiensis israelensis, AM625 strain, commercial name: VectoBac WDG [Valent Biosciences, Libertyville IL, USA]). Shipped from the USA to Malawi
^dManual labour donated by community members towards HI and LSM activities: closing eaves, gaps in walls, and fixing wire mesh; draining, filling and bacterial larvicide application to water bodies; mapping water bodies; and monitoring;
^eCommunity time attending village workshops (person-hours spent per workshop), valued using Malawi government minimum wage rate
^fIEC = Information, Education and Communication, including costs of printing and translation of educational material, implementation guides/manuals, etc. Other community engagement activities include community members labour towards disseminating messages about interventions (e.g. village ‘criers’ to inform community members of upcoming meetings
^gOther small equipment not meeting threshold for “capital” items (e.g. buckets for drawing water, hoes, shovels donated from communities). See (h)
^hCapital costs: Costs for items with a useful life of > 1 year and replacement value of > $100
